It 79 * can be used with {@link Context#startActivity(Intent) startActivity} to 80 * launch an {@link android.app.Activity}, 81 * {@link android.content.Context#sendBroadcast(Intent) broadcastIntent} to 82 * send it to any interested {@link BroadcastReceiver BroadcastReceiver} components, 83 * and {@link android.content.Context#startService} or 84 * {@link android.content.Context#bindService} to communicate with a 85 * background {@link android.app.Service}. 86 * 87 * <p>An Intent provides a facility for performing late runtime binding between the code in 88 * different applications. Its most significant use is in the launching of activities, where it 89 * can be thought of as the glue between activities. It is basically a passive data structure 90 * holding an abstract description of an action to be performed.</p> 91 * 92 * <div class="special reference"> 93 * <h3>Developer Guides</h3> 94 * <p>For information about how to create and resolve intents, read the 95 * <a href="{@docRoot}guide/topics/intents/intents-filters.html">Intents and Intent Filters</a> 96 * developer guide.</p> 97 * </div> 98 * 99 * <a name="IntentStructure"></a> 100 * <h3>Intent Structure</h3> 101 * <p>The primary pieces of information in an intent are:</p> 102 * 103 * <ul> 104 * <li> <p><b>action</b> -- The general action to be performed, such as 105 * {@link #ACTION_VIEW}, {@link #ACTION_EDIT}, {@link #ACTION_MAIN}, 106 * etc.</p> 107 * </li> 108 * <li> <p><b>data</b> -- The data to operate on, such as a person record 109 * in the contacts database, expressed as a {@link android.net.Uri}.</p> 110 * </li> 111 * </ul> 112 * 113 * 114 * <p>Some examples of action/data pairs are:</p> 115 * 116 * <ul> 117 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/1</i></b> -- Display 118 * information about the person whose identifier is "1".</p> 119 * </li> 120 * <li> <p><b>{@link #ACTION_DIAL} <i>content://contacts/people/1</i></b> -- Display 121 * the phone dialer with the person filled in.</p> 122 * </li> 123 * <li> <p><b>{@link #ACTION_VIEW} <i>tel:123</i></b> -- Display 124 * the phone dialer with the given number filled in. Note how the 125 * VIEW action does what is considered the most reasonable thing for 126 * a particular URI.</p> 127 * </li> 128 * <li> <p><b>{@link #ACTION_DIAL} <i>tel:123</i></b> -- Display 129 * the phone dialer with the given number filled in.</p> 130 * </li> 131 * <li> <p><b>{@link #ACTION_EDIT} <i>content://contacts/people/1</i></b> -- Edit 132 * information about the person whose identifier is "1".</p> 133 * </li> 134 * <li> <p><b>{@link #ACTION_VIEW} <i>content://contacts/people/</i></b> -- Display 135 * a list of people, which the user can browse through. This example is a 136 * typical top-level entry into the Contacts application, showing you the 137 * list of people. Selecting a particular person to view would result in a 138 * new intent { <b>{@link #ACTION_VIEW} <i>content://contacts/people/N</i></b> } 139 * being used to start an activity to display that person.</p> 140 * </li> 141 * </ul> 142 * 143 * <p>In addition to these primary attributes, there are a number of secondary 144 * attributes that you can also include with an intent:</p> 145 * 146 * <ul> 147 * <li> <p><b>category</b> -- Gives additional information about the action 148 * to execute. For example, {@link #CATEGORY_LAUNCHER} means it should 149 * appear in the Launcher as a top-level application, while 150 * {@link #CATEGORY_ALTERNATIVE} means it should be included in a list 151 * of alternative actions the user can perform on a piece of data.</p> 152 * <li> <p><b>type</b> -- Specifies an explicit type (a MIME type) of the 153 * intent data. Normally the type is inferred from the data itself. 154 * By setting this attribute, you disable that evaluation and force 155 * an explicit type.</p> 156 * <li> <p><b>component</b> -- Specifies an explicit name of a component 157 * class to use for the intent. Normally this is determined by looking 158 * at the other information in the intent (the action, data/type, and 159 * categories) and matching that with a component that can handle it. 160 * If this attribute is set then none of the evaluation is performed, 161 * and this component is used exactly as is. By specifying this attribute, 162 * all of the other Intent attributes become optional.</p> 163 * <li> <p><b>extras</b> -- This is a {@link Bundle} of any additional information. 164 * This can be used to provide extended information to the component. 165 * For example, if we have a action to send an e-mail message, we could 166 * also include extra pieces of data here to supply a subject, body, 167 * etc.</p> 168 * </ul> 169 * 170 * <p>Here are some examples of other operations you can specify as intents 171 * using these additional parameters:</p> 172 * 173 * <ul> 174 * <li> <p><b>{@link #ACTION_MAIN} with category {@link #CATEGORY_HOME}</b> -- 175 * Launch the home screen.</p> 176 * </li> 177 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 178 * <i>{@link android.provider.Contacts.Phones#CONTENT_URI 179 * vnd.android.cursor.item/phone}</i></b> 180 * -- Display the list of people's phone numbers, allowing the user to 181 * browse through them and pick one and return it to the parent activity.</p> 182 * </li> 183 * <li> <p><b>{@link #ACTION_GET_CONTENT} with MIME type 184 * <i>*{@literal /}*</i> and category {@link #CATEGORY_OPENABLE}</b> 185 * -- Display all pickers for data that can be opened with 186 * {@link ContentResolver#openInputStream(Uri) ContentResolver.openInputStream()}, 187 * allowing the user to pick one of them and then some data inside of it 188 * and returning the resulting URI to the caller. This can be used, 189 * for example, in an e-mail application to allow the user to pick some 190 * data to include as an attachment.</p> 191 * </li> 192 * </ul> 193 * 194 * <p>There are a variety of standard Intent action and category constants 195 * defined in the Intent class, but applications can also define their own. 196 * These strings use Java-style scoping, to ensure they are unique -- for 197 * example, the standard {@link #ACTION_VIEW} is called 198 * "android.intent.action.VIEW".</p> 199 * 200 * <p>Put together, the set of actions, data types, categories, and extra data 201 * defines a language for the system allowing for the expression of phrases 202 * such as "call john smith's cell". As applications are added to the system, 203 * they can extend this language by adding new actions, types, and categories, or 204 * they can modify the behavior of existing phrases by supplying their own 205 * activities that handle them.</p> 206 * 207 * <a name="IntentResolution"></a> 208 * <h3>Intent Resolution</h3> 209 * 210 * <p>There are two primary forms of intents you will use. 211 * 212 * <ul> 213 * <li> <p><b>Explicit Intents</b> have specified a component (via 214 * {@link #setComponent} or {@link #setClass}), which provides the exact 215 * class to be run. Often these will not include any other information, 216 * simply being a way for an application to launch various internal 217 * activities it has as the user interacts with the application. 218 * 219 * <li> <p><b>Implicit Intents</b> have not specified a component; 220 * instead, they must include enough information for the system to 221 * determine which of the available components is best to run for that 222 * intent. 223 * </ul> 224 * 225 * <p>When using implicit intents, given such an arbitrary intent we need to 226 * know what to do with it. This is handled by the process of <em>Intent 227 * resolution</em>, which maps an Intent to an {@link android.app.Activity}, 228 * {@link BroadcastReceiver}, or {@link android.app.Service} (or sometimes two or 229 * more activities/receivers) that can handle it.</p> 230 * 231 * <p>The intent resolution mechanism basically revolves around matching an 232 * Intent against all of the <intent-filter> descriptions in the 233 * installed application packages. (Plus, in the case of broadcasts, any {@link BroadcastReceiver} 234 * objects explicitly registered with {@link Context#registerReceiver}.) More 235 * details on this can be found in the documentation on the {@link 236 * IntentFilter} class.</p> 237 * 238 * <p>There are three pieces of information in the Intent that are used for 239 * resolution: the action, type, and category. Using this information, a query 240 * is done on the {@link PackageManager} for a component that can handle the 241 * intent. The appropriate component is determined based on the intent 242 * information supplied in the <code>AndroidManifest.xml</code> file as 243 * follows:</p> 244 * 245 * <ul> 246 * <li> <p>The <b>action</b>, if given, must be listed by the component as 247 * one it handles.</p> 248 * <li> <p>The <b>type</b> is retrieved from the Intent's data, if not 249 * already supplied in the Intent. Like the action, if a type is 250 * included in the intent (either explicitly or implicitly in its 251 * data), then this must be listed by the component as one it handles.</p> 252 * <li> For data that is not a <code>content:</code> URI and where no explicit 253 * type is included in the Intent, instead the <b>scheme</b> of the 254 * intent data (such as <code>http:</code> or <code>mailto:</code>) is 255 * considered. Again like the action, if we are matching a scheme it 256 * must be listed by the component as one it can handle. 257 * <li> <p>The <b>categories</b>, if supplied, must <em>all</em> be listed 258 * by the activity as categories it handles. That is, if you include 259 * the categories {@link #CATEGORY_LAUNCHER} and 260 * {@link #CATEGORY_ALTERNATIVE}, then you will only resolve to components 261 * with an intent that lists <em>both</em> of those categories. 262 * Activities will very often need to support the 263 * {@link #CATEGORY_DEFAULT} so that they can be found by 264 * {@link Context#startActivity Context.startActivity()}.</p> 265 * </ul> 266 * 267 * <p>For example, consider the Note Pad sample application that 268 * allows user to browse through a list of notes data and view details about 269 * individual items. Text in italics indicate places were you would replace a 270 * name with one specific to your own package.</p> 271 * 272 * <pre> <manifest xmlns:android="http://schemas.android.com/apk/res/android" 273 * package="<i>com.android.notepad</i>"> 274 * <application android:icon="@drawable/app_notes" 275 * android:label="@string/app_name"> 276 * 277 * <provider class=".NotePadProvider" 278 * android:authorities="<i>com.google.provider.NotePad</i>" /> 279 * 280 * <activity class=".NotesList" android:label="@string/title_notes_list"> 281 * <intent-filter> 282 * <action android:name="android.intent.action.MAIN" /> 283 * <category android:name="android.intent.category.LAUNCHER" /> 284 * </intent-filter> 285 * <intent-filter> 286 * <action android:name="android.intent.action.VIEW" /> 287 * <action android:name="android.intent.action.EDIT" /> 288 * <action android:name="android.intent.action.PICK" /> 289 * <category android:name="android.intent.category.DEFAULT" /> 290 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 291 * </intent-filter> 292 * <intent-filter> 293 * <action android:name="android.intent.action.GET_CONTENT" /> 294 * <category android:name="android.intent.category.DEFAULT" /> 295 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 296 * </intent-filter> 297 * </activity> 298 * 299 * <activity class=".NoteEditor" android:label="@string/title_note"> 300 * <intent-filter android:label="@string/resolve_edit"> 301 * <action android:name="android.intent.action.VIEW" /> 302 * <action android:name="android.intent.action.EDIT" /> 303 * <category android:name="android.intent.category.DEFAULT" /> 304 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 305 * </intent-filter> 306 * 307 * <intent-filter> 308 * <action android:name="android.intent.action.INSERT" /> 309 * <category android:name="android.intent.category.DEFAULT" /> 310 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 311 * </intent-filter> 312 * 313 * </activity> 314 * 315 * <activity class=".TitleEditor" android:label="@string/title_edit_title" 316 * android:theme="@android:style/Theme.Dialog"> 317 * <intent-filter android:label="@string/resolve_title"> 318 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 319 * <category android:name="android.intent.category.DEFAULT" /> 320 * <category android:name="android.intent.category.ALTERNATIVE" /> 321 * <category android:name="android.intent.category.SELECTED_ALTERNATIVE" /> 322 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 323 * </intent-filter> 324 * </activity> 325 * 326 * </application> 327 * </manifest></pre> 328 * 329 * <p>The first activity, 330 * <code>com.android.notepad.NotesList</code>, serves as our main 331 * entry into the app. It can do three things as described by its three intent 332 * templates: 333 * <ol> 334 * <li><pre> 335 * <intent-filter> 336 * <action android:name="{@link #ACTION_MAIN android.intent.action.MAIN}" /> 337 * <category android:name="{@link #CATEGORY_LAUNCHER android.intent.category.LAUNCHER}" /> 338 * </intent-filter></pre> 339 * <p>This provides a top-level entry into the NotePad application: the standard 340 * MAIN action is a main entry point (not requiring any other information in 341 * the Intent), and the LAUNCHER category says that this entry point should be 342 * listed in the application launcher.</p> 343 * <li><pre> 344 * <intent-filter> 345 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 346 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 347 * <action android:name="{@link #ACTION_PICK android.intent.action.PICK}" /> 348 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 349 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 350 * </intent-filter></pre> 351 * <p>This declares the things that the activity can do on a directory of 352 * notes. The type being supported is given with the <type> tag, where 353 * <code>vnd.android.cursor.dir/vnd.google.note</code> is a URI from which 354 * a Cursor of zero or more items (<code>vnd.android.cursor.dir</code>) can 355 * be retrieved which holds our note pad data (<code>vnd.google.note</code>). 356 * The activity allows the user to view or edit the directory of data (via 357 * the VIEW and EDIT actions), or to pick a particular note and return it 358 * to the caller (via the PICK action). Note also the DEFAULT category 359 * supplied here: this is <em>required</em> for the 360 * {@link Context#startActivity Context.startActivity} method to resolve your 361 * activity when its component name is not explicitly specified.</p> 362 * <li><pre> 363 * <intent-filter> 364 * <action android:name="{@link #ACTION_GET_CONTENT android.intent.action.GET_CONTENT}" /> 365 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 366 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 367 * </intent-filter></pre> 368 * <p>This filter describes the ability to return to the caller a note selected by 369 * the user without needing to know where it came from. The data type 370 * <code>vnd.android.cursor.item/vnd.google.note</code> is a URI from which 371 * a Cursor of exactly one (<code>vnd.android.cursor.item</code>) item can 372 * be retrieved which contains our note pad data (<code>vnd.google.note</code>). 373 * The GET_CONTENT action is similar to the PICK action, where the activity 374 * will return to its caller a piece of data selected by the user. Here, 375 * however, the caller specifies the type of data they desire instead of 376 * the type of data the user will be picking from.</p> 377 * </ol> 378 * 379 * <p>Given these capabilities, the following intents will resolve to the 380 * NotesList activity:</p> 381 * 382 * <ul> 383 * <li> <p><b>{ action=android.app.action.MAIN }</b> matches all of the 384 * activities that can be used as top-level entry points into an 385 * application.</p> 386 * <li> <p><b>{ action=android.app.action.MAIN, 387 * category=android.app.category.LAUNCHER }</b> is the actual intent 388 * used by the Launcher to populate its top-level list.</p> 389 * <li> <p><b>{ action=android.intent.action.VIEW 390 * data=content://com.google.provider.NotePad/notes }</b> 391 * displays a list of all the notes under 392 * "content://com.google.provider.NotePad/notes", which 393 * the user can browse through and see the details on.</p> 394 * <li> <p><b>{ action=android.app.action.PICK 395 * data=content://com.google.provider.NotePad/notes }</b> 396 * provides a list of the notes under 397 * "content://com.google.provider.NotePad/notes", from which 398 * the user can pick a note whose data URL is returned back to the caller.</p> 399 * <li> <p><b>{ action=android.app.action.GET_CONTENT 400 * type=vnd.android.cursor.item/vnd.google.note }</b> 401 * is similar to the pick action, but allows the caller to specify the 402 * kind of data they want back so that the system can find the appropriate 403 * activity to pick something of that data type.</p> 404 * </ul> 405 * 406 * <p>The second activity, 407 * <code>com.android.notepad.NoteEditor</code>, shows the user a single 408 * note entry and allows them to edit it. It can do two things as described 409 * by its two intent templates: 410 * <ol> 411 * <li><pre> 412 * <intent-filter android:label="@string/resolve_edit"> 413 * <action android:name="{@link #ACTION_VIEW android.intent.action.VIEW}" /> 414 * <action android:name="{@link #ACTION_EDIT android.intent.action.EDIT}" /> 415 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 416 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 417 * </intent-filter></pre> 418 * <p>The first, primary, purpose of this activity is to let the user interact 419 * with a single note, as decribed by the MIME type 420 * <code>vnd.android.cursor.item/vnd.google.note</code>. The activity can 421 * either VIEW a note or allow the user to EDIT it. Again we support the 422 * DEFAULT category to allow the activity to be launched without explicitly 423 * specifying its component.</p> 424 * <li><pre> 425 * <intent-filter> 426 * <action android:name="{@link #ACTION_INSERT android.intent.action.INSERT}" /> 427 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 428 * <data android:mimeType="vnd.android.cursor.dir/<i>vnd.google.note</i>" /> 429 * </intent-filter></pre> 430 * <p>The secondary use of this activity is to insert a new note entry into 431 * an existing directory of notes. This is used when the user creates a new 432 * note: the INSERT action is executed on the directory of notes, causing 433 * this activity to run and have the user create the new note data which 434 * it then adds to the content provider.</p> 435 * </ol> 436 * 437 * <p>Given these capabilities, the following intents will resolve to the 438 * NoteEditor activity:</p> 439 * 440 * <ul> 441 * <li> <p><b>{ action=android.intent.action.VIEW 442 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 443 * shows the user the content of note <var>{ID}</var>.</p> 444 * <li> <p><b>{ action=android.app.action.EDIT 445 * data=content://com.google.provider.NotePad/notes/<var>{ID}</var> }</b> 446 * allows the user to edit the content of note <var>{ID}</var>.</p> 447 * <li> <p><b>{ action=android.app.action.INSERT 448 * data=content://com.google.provider.NotePad/notes }</b> 449 * creates a new, empty note in the notes list at 450 * "content://com.google.provider.NotePad/notes" 451 * and allows the user to edit it. If they keep their changes, the URI 452 * of the newly created note is returned to the caller.</p> 453 * </ul> 454 * 455 * <p>The last activity, 456 * <code>com.android.notepad.TitleEditor</code>, allows the user to 457 * edit the title of a note. This could be implemented as a class that the 458 * application directly invokes (by explicitly setting its component in 459 * the Intent), but here we show a way you can publish alternative 460 * operations on existing data:</p> 461 * 462 * <pre> 463 * <intent-filter android:label="@string/resolve_title"> 464 * <action android:name="<i>com.android.notepad.action.EDIT_TITLE</i>" /> 465 * <category android:name="{@link #CATEGORY_DEFAULT android.intent.category.DEFAULT}" /> 466 * <category android:name="{@link #CATEGORY_ALTERNATIVE android.intent.category.ALTERNATIVE}" /> 467 * <category android:name="{@link #CATEGORY_SELECTED_ALTERNATIVE android.intent.category.SELECTED_ALTERNATIVE}" /> 468 * <data android:mimeType="vnd.android.cursor.item/<i>vnd.google.note</i>" /> 469 * </intent-filter></pre> 470 * 471 * <p>In the single intent template here, we 472 * have created our own private action called 473 * <code>com.android.notepad.action.EDIT_TITLE</code> which means to 474 * edit the title of a note. It must be invoked on a specific note 475 * (data type <code>vnd.android.cursor.item/vnd.google.note</code>) like the previous 476 * view and edit actions, but here displays and edits the title contained 477 * in the note data. 478 * 479 * <p>In addition to supporting the default category as usual, our title editor 480 * also supports two other standard categories: ALTERNATIVE and 481 * SELECTED_ALTERNATIVE.
